Package rr: Information

rr is a lightweight tool for recording, replaying and debugging execution
of applications (trees of processes and threads). Debugging extends gdb
with very efficient reverse-execution, which in combination with standard
gdb/x86 features like hardware data watchpoints, makes debugging much
more fun.

rr currently requires either:

- An Intel CPU with Nehalem (2010) or later microarchitecture.
- Certain AMD Zen or later processors.
- Certain AArch64 microarchitectures (e.g. ARM Neoverse N1 or the Apple
  Silicon M-series).
